Sportscar racing is a complicated beast at the best of times, and especially so when two competing series combine into one.

That is what has happened to North American sportscar racing in 2014. I hope this post will help de-mystify this brand new series and will go some way to explaining what is happening.

What Is It?

Name:  IMSA TUDOR United Sportscar Championship

Shorter Name: The officials seem happiest with “TUDOR Championship“, while fans and media are referring to it either as “TUSC“, or in a nod to the glory days of the 1980s, “IMSA“. Technically IMSA are the people setting the rules, and not the series itself, so when I say IMSA I mean the people running things.

Where Did It Come From?

The TUDOR Championship is a merger of these two series:
– American Le Mans Series (ALMS)
– Grand-Am Rolex Series (GA)

What Classes?

P – Prototype:
Daytona Prototypes from GA are combined with LMP2 cars from the ALMS, and the DeltaWing, all in one single class.
The LMP1 cars have been abolished, as of now you can only see LMP1 in the World Endurance Championship (WEC).
DPs have been sped up with more downforce. P2 cars have been slowed a little with Continental tyres (reckoned to be slower than Michelins & Dunlops used in WEC). The DPs will have an advantage at Daytona, which you would expected of cars called ‘Daytona Prototypes’. The P2s will regain the balance the rest of the year. Pro driver class, as denoted by red screen and mirrors.

PC – Prototype Challenge:
This is identical to the PC class in the ALMS. No changes. A budget class for spec cars to promote ‘gentlemen’/amateur drivers, who hire hot talent to make them go fast. Pro-Am class, as denoted by blue screen and mirrors.

GTLM – Grand Touring Le Mans:
This is the ALMS GT class. Nothing was changed since last year, and this is the only class not running Continental tyres. The specs are identical to Le Mans and the WEC’s GTE class, hence the Le Mans moniker. The only thing new are brand new cars from Corvette and Porsche. Pro driver class, as denoted by red screen and mirrors.

GTD – Grand Touring Daytona:
Ostensibly the old Grand-Am GT class merged with the ALMS GTC Porsches, but with modified – slowed down – GT3 cars added into it. In reality the old-style GA GT cars and the GTC Porsches are gone. This class is 25+ GT3 cars, albeit with a TUSC-mandated rear wing producing less downforce than FIA GT3 rules allow, and without many of the TC and electronics the FIA rules allow. Ferraris, Porsches, BMWs, Aston Martins. With so many cars this is potentially the most fun class. Pro-Am class, as denoted by blue screen and mirrors.

No longer racing:
LMP1 cars from the ALMS, and GX cars from Grand-Am. Neither class has a home in TUSC.

Where Do They Race?

The four endurance races from both series:

Daytona 24 Hours, Sebring 12 Hours, Watkins Glen 6 Hours, Petit Le Mans. Those four endurance races make up the North American Endurance Championship (NAEC).

Add in Long Beach, Detroit, Laguna Seca, Road America, Mosport. This is the most exciting sportscar schedule in the world right now.

Who Is In It?

P – Chip Ganassi, Extreme Speed, DeltaWing, Action Express, Muscle Milk Pickett, Wayne Taylor Racing, Starworks, Shank, Spirit of Daytona, and even OAK Racing sent a team for a full season.
PC – Starworks, 8Star, PR1/Mathiason, Performance Tech, BAR1, RSR.
GTLM – Corvette, SRT Viper, BMW Team RLL, Risi Ferrari, Porsche North America (run by CORE).
GTD – Dempsey, Magnus, Alex Job, NGT, GMG, Fall-Line, Park Place, Turner, Scuderia Corse.

Dyson Racing is notably absent now – but they WILL be back.

And nearly all the drivers you already know from both series.

Exciting?

Absolutely!
